Abstract
Systems and methods for processing a detected composite color image to form a processed composite color image includes the following, for each of a plurality of pixels in the image: (1) identifying a window of pixels in the image that surrounds the pixel, (2) calculating a weight factor coefficient for each detected color from detected color intensity values of the pixels that surround the pixel, (3) calculating raw color contributions corresponding to each nonselected color, (4) multiplying each of the detected color values of a selected color and the raw color contributions corresponding to the nonselected colors, with corresponding weight factor coefficients, to form weighted color contributions, and (5) summing the weighted color contributions to form a processed color intensity value for the pixel.
